Which medication is most appropriate for acute bronchospasm in the field?

Acute bronchospasm requires rapid bronchodilation, so the best field-appropriate medication is a fast-acting inhaled bronchodilator. Albuterol is a short-acting beta-2 agonist that binds receptors on bronchial smooth muscle, increases cyclic AMP, and quickly relaxes the airway muscles. This rapid relaxation opens the airways, lowers airway resistance, and improves breathing within minutes, which is exactly what’s needed during a bronchospasm emergency. It’s commonly delivered by inhaler or nebulizer and can be repeated per protocol if symptoms persist. Diphenhydramine won’t reverse bronchoconstriction and can cause sedation; acetaminophen doesn’t affect airway tone; furosemide is a diuretic with no role in treating acute bronchospasm.
